IG Metall (German: Industriegewerkschaft Metall, "Industrial Union of Metalworkers'") is the dominant metalworkers' union in Germany. Analysts of German labor relations consider it a major trend-setter in national bargaining. As a metalworkers' union, it represents workers in the motor vehicle industry. Significantly, IG Metall represents both blue- and white-collar workers.
On April 1, 1998 the Gewerkschaft Textil und Bekleidung (GTB), the trade union of textile and clothing joined IGM.
On January 1, 2000 the Gewerkschaft Holz und Kunststoff (GHK), the trade union of wood and plastics joined IGM.
IGM is a member of the German Confederation of Trade Unions (Deutscher Gewerkschaftsbund, DGB). IGM is also a member of some international union umbrella organisations.
